It's designed with the real world in mind. The Atlas ESR is the only instrument that automatically detects charged capacitors and then performs a controlled discharge process before measuring the capacitance and ESR.
Measuring a capacitor's ESR (equivalent series resistance) is a great indicator of capacitor condition. This portable unit offers instant results, just connect the probes and press test. Innovative audible alerts give you an instant feedback of the measurement results with further detail shown on the screen.
And the tones themselves are surprising pleasant, including “Bell-like” pings (a couple of different types for ESR that is below certain values), and also a “Beep-Barp” type tone for ESR that is likely to be too high. There is also a reassuring “Blip” when the measurement has started and completed.
You can even use directly in-circuit, saving you the trouble of removing capacitors. When testing capacitors out-of circuit, the unit will also display the capacitance.
